2 Claims.

This invention relates to window elements and more particularly to alocking means therefor, as originally disclosed in my application filedJune 30, 1936, Serial Number 88,230, of which this application is adivisional application.

One of the important objects of this invention is the production of asimple and efficient means for locking the upper and lower window sashesand remotely anchoring the locking means in a manner whereby theanchoring means will be shielded from view from the outside of thewindow.

A further object of this invention is the production of a simple andefiicient lock which is so constructed as to firmly draw the upper andlower sashes together in a locked position as the hook is swung to alocking position.

Other objects and advantages of this invention will appear throughoutthe following specification and claims.

In the drawing:

Figure 1 is a front elevation of a window showing my improved lockingdevice applied thereto;

Figure 2 is a horizontal sectional view taken on line 2-2 of Figure 1;

Figure 3 is an enlarged horizontal sectional view taken on line 3-3 ofFigure 2;

Figure 4 is a vertical sectional view taken on line 4-4 of Figure 1;

Figure 5 is a perspective view of the hook engaging link;

Figure 6 is a perspective view of the locking hook.

By referring to the drawing, it will be seen that A designates thewindow frame which may be of the type of structure such as is shown. Incarrying out my invention, I preferably slidably mount an upper sashframe I0 within the window frame or casing A, and also slidably mount alower sash frame II within the window frame or casing A. These sashframes Ill and II may be connected to the counter-weights I2 through themedium of suitable sash cords. The upper sash I0 is provided with asuitable screen Illa and a burglar guard I019. The lower sash II is alsoprovided with a screen Ila and a burglar guard IIb, similar to myprevious application Serial Number 88,230.

The bottom sash frame II is provided along or adjacent its top edge witha transversely extending elongated aperture I3, in which is pivotallymounted a locking hook I4, as at I5, the locking hook I4 having anoffset arm I6 which terminates in a hook end II. The inner face I8 of 66the offset arm I6 is inclined with respect to the longitudinal axis ofthe shank I9, the outer end which terminates in the hook Il being insubstantial alignment with the pivot I5, and the shank I9. A pin 20, isextended vertically through a socket 2I formed in the face of the sashII] which 6 abuts the sash I I, and is adapted to be engaged by the hookand the offset arm I6. It will therefore be seen that as the hook I4 isswung in the direction of the arrow shown in Figure 3, the

v inclined face I8 of the offset arm I6 by engag- 10 ing the pin 20,will cause the sashes I0 and II to be drawn tightly together. The harderthe pull in the direction of the arrow shown in Figure 3, the tighterthe clamping action of the hook I1 and arm I6 upon the pin 20. 1

The shank I9 normally extends outwardly beyond the sash II projectingfrom the elongated aperture I3 and the outer end of the shank I9 carriesa vertically extending pin 22, which pin extends above andbelow theshank I9, as shown 20 in Figures 4 and 6.

An elongated link 23 engages the shank I9 and is provided with anelongated slot 24 through which the shank I9 extends, the slot 24terminating at one end in a right-angularly extending slot 25 25 forpermitting the vertically extending pin 22 to pass therethrough in avertical position and to allow the shank I9 to slide longitudinallythrough the slot 24, thus providing an efficient detachable connectionbetween the link 23 and the shank I9. The link 23 is engaged near thetransverse or vertical slot 25 by means of an anchoring chain 26. Thischain 26 carries a snap hook 21 at its outer end for engaging the eye 28of an anchoring plate 29. The anchoring plate 29 is prefer- 35 ablypositioned to the wall, at one side of the window frame or casing A, asshown in Figure 1, in transverse alignment with the overlapping portionsof the upper and lower sashes I0 and I I and in substantial alignmentwith the link 23 and 40 hook I4 so as to extend the chain 26 across theinner face of the window and in close proximity to the overlappingportions of the sash. In this way the anchoring chain 26 will beanchored at a considerable distance from the window sash 45 beyond reachof an unauthorized party reaching through the window from the outside.

It should be further understood that the hook I4 may not be swung to anopen position until the snap hook 21 is released with the chain 26, 50since the plate 29 and eye 28 are located at a selected position to holdthe chain 26 taut when the hook I4 engages the pin 20 in a lockingposition, such as is shown in Figures 1, 2 and 3. Furthermore, it willbe seen that when it is desired, 5|

Having described the invention, what I claimas new is:

1. A fastener for Window sashes and the like comprising a locking hookhaving a pivot sup-'- port adapted to be carried by one sash and, meanscarried by the hook for engaging means on an adjoining sash for lockingtwo adjoining sashes together, said locking hook having an elongatedshank adapted to project beyond one sash, the outer end of the shankhaving right angularly extending stop means, an elongated detachablelink having a T-shaped slot for receiving the outer end of the shank,the right angularly extending stop means of the shank being adapted toenter the slot at one end and adapted to overhang the sides of the slotas the shank is moved 1ongitudinally of the slot for detachably holdingthe link in engagement with the shank, and flexible anchoring meanscarried by the link and adapted to be secured remotely at one end forholding said locking hook in a set position.

2. A fastener for window sashes and the like, comprising a locking hookadapted to be pivoted upon one sash and having means for lockingengagement with an adjoining sash, said looking hook having an elongatedshank adapted to project beyond the sash on which the hook is adapted tobe mounted, a detachable link fitting over said shank, and a remotelyanchored flexible means secured to said link for holding said link and'alocking hook against swinging movement in one direction.
